I don't know that I would say they're contributing to childhood obesity, but I do think it's crazy to call a 10 year old an adult. We stopped getting the dining plan years ago, we prefer to just order what we want which may be a salad and appetizer instead of an entree, prefer an ice cream walking around the park to dessert with out meal, etc..
My son hit six feet tall just before he turned 10 years old. The children's menu was not enough. Feeding him was an adventure!
I agree, to a point. Parents are responsible for teaching their kids restraint and healthy choices, but restaurants should also be held to account once in awhile, particularly when their practices are subtle or insidious. Adding sugar, for example, to breading, so you get the addictive combination of fat and sugar that makes food irresistible, or marketing directly to kids. Honestly, I feel sometimes that if we don't allow Joe the Camel to advertise cigs to kids, we shouldn't allow Ronald McDonald either.
During this most recent trip we did do a few table service meals around lunch time to get out of the heat. One of those was 50's Prime Time Cafe in Hollywood Studios. My eleven year old cried when it was time to order, he wanted to order off the kids menu and was told no because "you are not a kid, you are too old" but that they would bring him an adult portion of the mac and cheese he wanted. He is my Peter Pan Neverland boy and loves being a kid and hates the idea of being an adult, so to have his most favorite place on earth tell him he is not kid anymore near broke his heart. So my eleven year was served an extra large portion of the mac and cheese with no healthy sides (that a kids meal comes with) and we were charged over double what the kids meal cost
Pay OOP instead of buying the DDP.
